         * Class: $.jqplot.MeterGaugeRenderer
         * Plugin renderer to draw a meter gauge chart.
         *
         * Data consists of a single series with 1 data point to position the gauge needle.
         *
         * To use this renderer, you need to include the
         * meter gauge renderer plugin, for example:
         *
         * > <script type="text/javascript" src="plugins/jqplot.meterGaugeRenderer.js"></script>
         *
         * Properties described here are passed into the $.jqplot function
         * as options on the series renderer.  For example:
         *
         * > plot0 = $.jqplot('chart0',[[18]],{
     * >     title: 'Network Speed',
     * >     seriesDefaults: {
     * >         renderer: $.jqplot.MeterGaugeRenderer,
     * >         rendererOptions: {
     * >             label: 'MB/s'
     * >         }
     * >     }
     * > });
         *
         * A meterGauge plot does not support events.
